Subject: [PATCH] arch/x86/realmode: make trampoline code conditional for x86-32
Date: Wed, 15 Oct 2014 17:38:26 +0200 [thread overview]
Message-ID: <1413387506-5269-1-git-send-email-jarkko.sakkinen@linux.intel.com> (raw)
Trampoline code is only needed for SMP and in x86-64 for wakeup
code. Make it conditional in order to minimize the kernel size.
